Get Your API Key

To use server-side features (importance ranking, smart filtering), you'll need an API key:

1. Sign up at predicatesystems.ai
2. Navigate to API Keys section in your dashboard
3. Create a new API key (starts with sk_)
4. Set it as an environment variable or pass it to the SDK

Environment variable (recommended):

export PREDICATE_API_KEY="sk_..."

Free Tier Available

You can use the SDK without an API key for both local & cloud based processing with your free credits:

• All SDK functions work
• Limited server API calls (no credit card required)
• Full importance ranking within free credit limits
• Full smart filtering within free credit limits

Upgrade to Pro, Builder, Teams, or Enterprise tier when you need production-grade ranking and filtering.

Troubleshooting

"Extension failed to load"

The Predicate extension should be automatically loaded. If you see this error:

• Ensure Playwright Chromium is installed: playwright install chromium
• Check that you have the latest SDK version
• Try reinstalling: pip install --upgrade predicate-sdk or npm install @predicatesystems/sdk

"ModuleNotFoundError" (Python)

Make sure you're using the correct Python environment:

python --version  # Check Python version
pip --version     # Check pip is available
pip install predicate-sdk  # Install in current environment
